Question about Gateway FPD2275W LCD Monitor
I have samsung 591 monitor. It has a problem that the relay is in oscillating condition.It does not have stable state giving the sound "cut-cut'
Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.

Tips for a great answer:
This can be possible fault with the output circuit as the blinking is in oscillation. Also with many sets when it goes old as there is a high possibility that the components over a period of heating and cooling , tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs.
Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points.
if not the fault can be poor capacitors- try heating to see if the oscialltions stop- or even failure of IC
